1. Introduction

Due to the high incidence of lung cancer in octogenar-ians, surgeons are increasingly confronted with the clin-ical challenge of how best to treat these patients withresectable lung cancer. Fourteen percent of patients diag-nosed with lung cancer in the United States from 1988–2003were ≥80 years old [1] with the peak incidence occurringbetween ages 75–79 [2]. With the general population livinglonger and the baby boomer generation reaching this agebracket in the next decade, it is imperative that we betterunderstand complications and survival in this growing agegroup.

Making optimal treatment recommendations can be chal-lenging for treating physicians as octogenarians in generalhave more comorbidities and a worse performance status

than the younger population. While the gold standard sur-gical therapy for early stage lung cancer remains anatomicresection [3], physicians may be hesitant to refer thesepatients for surgical evaluation and other treatment optionsincluding stereotactic body radiation therapy (SBRT) andwedge resection may be suggested [4]. Currently, long-termsurvival data for SBRT are limited and show a wide rangeof survival ranging from a 3-year survival of 42% for stageI [5] to 83% for stage IA [6] (see Table 4). In addition, thesurgical literature regarding octogenarians with lung canceris diverse and often includes patients with a wide varietyof clinical stages and resections (i.e., wedge, lobectomy, andpneumonectomy). As a result, broad 5-year survival ratesranging from 18.2% to 69.6% [7–17] have been reportedwhichare likely strongly related to variable inclusion data and extentof resection (see Table 3).

Prior publications have documented that octogenariansexperience higher complication rates after lung resectionwhich ranges from 8.4 to 68.8% [7–14, 16–19]. Data regardingthe severity, morbidity, or impact of those complications hasyet to be elucidated using a standardized validated system,leaving physicians with an incomplete understanding ofassessing short-term surgical risks versus long-term benefit.Furthermore, surgeons lack the data that allow them tocharacterize morbidity and complications beyond “major orminor” when counseling their patients. In order to reconcilethis, the Seely morbidity and mortality schema was designedfor application to thoracic surgical patients [20]. It providesa standardized and validated framework for physicians todescribe complications based on the level of interventionrequired [20].

Defining complication severity is important in the over-eighty population to allow for accurate patient counselingregarding surgical outcomes and to guide surgical treatmentalgorithms. We sought to gain further understanding of theinherent morbidity assumed by an octogenarian deemedappropriate for lobectomy and to characterize complicationsbased on a validated thoracic surgery schema. Furthermore,we assessed long-term survival to contextualize more com-pletely short-term risks versus long-term survival.

2. Methods

We performed a single center retrospective review of con-secutive patients aged eighty or greater who underwentlobectomy approached by thoracotomy, video assisted tho-racoscopic surgery (VATS), or robotic assisted methodsbetween 2004 and 2012. All patients were staged accordingto the American Joint Committee on Cancer (AJCC) 7thedition guidelines [21]. The Institutional Review Board (IRB)approved the study and data was entered into a securedatabase. Individual patient consent was waived due to theretrospective nature of the study.

Key data elements included age, gender, body massindex (BMI), comorbidities, percent of predicted forcedexpiratory volume expired in 1 second (FEV1), percent ofpredicted diffusion capacity of carbon dioxide (DLCO),operative approach, conversion of minimally invasive oper-ative approach to thoracotomy, mean operative time, meanestimated blood loss, intraoperativemortality, complications,intensive care unit (ICU) stay, clinical and pathologic stage,procedure performed, hospital length of stay (LOS), posthos-pital patient disposition to home or skilled nursing facility(SNF), follow-up duration, disease recurrence, patient status(living or deceased), and cause of death if applicable.

Patients were staged as follows. Cross sectional imagingwas used to determine tumor size and clinical T stage (cT).Clinical node negative status (cN0) was determined if thepatient had a standardized uptake value (SUV) <1.5 onpositron emission tomography (PET), a biopsy of a PETpositive node that was ultimately pathologically benign, orbiopsy of lymph node(s) > 1 cm in largest diameter that waspathologically benign.

Each attending surgeon determined patient operabil-ity based on the patient’s preoperative imaging, medical

comorbidities, activity tolerance, pulmonary function test-ing, and nutrition status. Specifically, this included patientswith an ECOG score of 0 or 1, a FEV1 and DLCO > 40%predicted after lobectomy, and no anginal symptoms. Patientswith a significant cardiac history or questionable cardiacreserve were referred to their cardiologist or newly evaluatedfor clearance to tolerate a surgery and general anesthetic.Each patient performed an in-office stair walk where heartrate and oxygen saturation were recorded while walking atleast two flights of stairs. Patients who became significantlydyspneic or had an oxygen saturation less than 92% whilewalking two flights were considered inoperable. No comor-bidity precluded consideration for an operation; however,care was taken to optimize these conditions (i.e., bloodglucose and pulmonary function) prior to consideration ofsurgery. This assessment determined the ability of a patientto tolerate general anesthetic and a lobectomy through anymodality. Once operability was determined, the decision toproceed with a thoracotomy or minimally invasive (VATS orrobotic) procedure was at the surgeon’s discretion.

We employed the Seely classification system, whichcharacterizes complication severity based on the need forgeneral anesthesia separating minor from major complica-tions. Grade I complications include any complication notrequiring intervention; grade II complications include anycomplication requiring pharmacologic intervention; gradeIIIA complications include any intervention not requiringgeneral anesthesia. Major complications were defined asgrade IIIB (any complication requiring general anesthesia),grade IV (any complication requiring ICU admission, singleorgan failure, or reintubation), and grade V (complicationsleading to death) (see Table 2).

Clinical follow-up was calculated from the date of dis-charge to the last clinic visit. In cases where a patient waslost to follow-up, status was verified by using the socialsecurity death registry and/or by contacting their primarycare physician. Survival data was analyzed by the Kaplan-Meier method. A univariate analysis was performed to iden-tify factors that influence overall survival including medicalcomorbidities, clinical and pathologic stages, tumor size, andcomplications (all and severe ≥IIIB). Statistical analyses werecompleted using SPSS 18.

3. Results

A total of 45 (male = 23) patients underwent lobectomy.No patients received neoadjuvant therapy prior to resection.Themost common comorbidity was hypertension (56%) (seeTable 1). All patients were high functioning with an ECOG of0 (39/45, 86.7%) and 1 (6/45, 13.3%). The majority of patients(42/45, 93.3%) underwent preoperative cardiac evaluationby a cardiologist. Nearly all patients were clinically stagedwith a diagnostic chest CT and PET. Thirty-nine patients(86.7%) underwent preoperative cervical mediastinoscopy.Clinical staging information was available for 41/45 patients.Of these, 20 were stage IA (51%), 8 stage IB (21%), 5stage IIA (11%), 1 stage IIB (2.2%), and 5 stage IIIA (11%).Two patients underwent lobectomies for metastasectomy,and staging information was unavailable for the remaining

four patients. All patients undergoing lobectomy for lungcancer were clinically node negative and without evidence ofmetastasis (cN0 and cM0) prior to resection.

Thoracotomy was performed most commonly (27/45,60.0%) followed by VATS (12/45, 26.7%) and robotic assisted(3/45, 6.7%). In two cases (2/15, 13.3%), a minimally invasiveapproach was converted to thoracotomy. Mean operativetime was 228 minutes (range 106–381 minutes) and meanestimated blood loss was 50mL. There was no intraoperativemortality. Disposition data was available for 32/45 patientsand 27/32 (84.4%) were admitted to the ICU postoperatively.The average ICU LOS was 3 days (range 1–13).

The pathology for most patients was non-small-cell lungcancer (NSCLC) (39/45, 86.7%) and the majority of thesewere adenocarcinoma (26/39, 66.7%). Two patients hadmetastatic disease from an extrathoracic source (colorectaland uterine stromal cell carcinoma) and 2 patients had aspindle cell neoplasm (one bronchioloalveolar carcinoma andone neuroendocrine tumor). In keepingwith the early clinicalstage of this population, the most common pathologic stagein the NSCLC patients was IB (13/39, 33.3%). Ten patients(10/39, 25.6%) were IA; 3 patients were IIA (3/39, 7.7%); 3patients were IIB (3/39, 7.7%); 7 patients were IIIA (7/39, 18%);1 patient was IIIB (1/39, 2.6%), and 2 patients were Stage IV(2/39, 5.1%) on final pathology.

Minor complications (grades I–IIIA) occurred in 46.7%(21/45) of patients. New onset atrial fibrillation requiringmedical therapy was the most common complication (22.2%,10/45). Ten patients (22.2%) had a prolonged air leak or fluidcollection that necessitated chest tube for > 5 days. Nine ofthese air leaks resolved while the patient was in hospital, but1 patient was discharged home with a chest tube due to apersistent leak. Four patients (8.9%)were discharged from thehospital with supplemental oxygen therapy per nasal cannula.

Severe postoperative complications (≥IIIB) occurred in15.6% (7/45) of patients. Three patients (6.7%) developed

pneumonia requiring ICU care. Two patients (4.4%) requiredreturn to the operating room for control of postoperativehemorrhage within twenty-four hours of the initial opera-tion. Additional severe complications included myocardialinfarction (2/45, 4.4%) and one inpatient sustained an anklefracture due to a fall, which subsequently required operativefixation (see Table 2). Furthermore, 1 patient (2.2%) withsteroid-dependent COPD died in the perioperative periodon postoperative day 13 due to sepsis induced multiple organsystem failure.

Over half of the patients had a postoperative complicationof some sort (28/45, 62%). Additional complications not cap-tured in the Seely classification system included unexpectedtransfers to the ICU for cardiac monitoring due to atrialfibrillation which occurred in 3/45 (6.7%). Thirty-six of the45 patients had disposition data available. Of these patients,88.9% (32/36) were able to be discharged home and 11.1%(4/36) were discharged to a skilled nursing facility.

During the mean follow-up period of 53 months (range1 week to 84 months), 13.3% (6/45) had disease recurrenceat a mean of 25 months from their operation (4 months–84months) and 51.1% (23/45) died. Causes of death includedlung cancer recurrence in 43.5% (10/23), multiorgan systemfailure in the perioperative period, stroke, amiodarone tox-icity, and sepsis (1 each). Nine patients died of unknowncauses.Mean 5-year overall survival calculated by theKaplan-Meier method was 52%. Medical comorbidities, clinicalstage, tumor size, any complication (grades I–V), and severecomplications (≥IIB) did not significantly influence survivalon univariate analysis.

4. Discussion

While anatomic lung resection remains the standard of carefor the treatment of NSCLC [3], octogenarians are lesslikely to be offered a lobectomy than younger patients. ASurveillance, Epidemiology and End Results (SEER) databasereview of 45,912 of patients aged ≥80 demonstrated thatoctogenarians were twice as likely to receive no local tumorspecific therapy (radiation or surgery) when compared toyounger patients despite a comparable rate of early stagecancers in both groups [1]. This was even significant whencomparing octogenarians to patients aged 70–79 (47%offeredno radiation or surgery versus 28%) [1]. Another studydemonstrated the same trend and showed that as ageincreases, patients undergo anatomic resection less often thanthe general population and are offered radiation therapymoreoften than surgery [22] despite the fact that radiation therapyor nonanatomic lung resection remains second line therapyfor patients with operable NSCLC [3].

Even with improvement in radiation methods fromexternal beam radiation therapy, stereotactic body radiation(SBRT), or stereotactic ablative radiation therapy (SABR)[23], resection offers the best chance for local control [24].In studies including octogenarians who are surgically ormedically inoperable, treatment decisions are a bit easier forhealthcare providers. This study sought to understand andclarify the risks and outcomes of the gold standard therapy(resection) within this group.

There has been a broad attempt across the surgicalliterature to classify complications by severity in order tostandardize complication reporting. The National CancerInstitute Common Terminology Criteria for Adverse Events(CTCAE) is a system which grades adverse events acrossmultiple diverse areas of medical care on a 1–5 scale [25]. Thevalidated Clavien-Dindo complication classification schemewas created for application to general surgery patients andis graded based upon the level of intervention required totreat the complication, a more practical system than simplyseparating events into major and minor categories [19].Seely et al. published a validated extension of the Clavien-Dindo system for application to the thoracic surgery patientpopulation [20]. Like the CTCAE, complications are gradedfrom I to V based on the level of intervention required totreat the complication, with minor complications consideredgrades I-II and major complications that result in significantmorbidity listed as grades III–V [20]. We used Seely gradein order to provide us with a specific understanding of thepractical morbidity faced by octogenarian population whenundergoing lung resection.

Lower % predicted FEV1 [19], thoracotomy as approach[9, 19], resection greater than wedge [19, 26], and medi-astinal lymph node dissection [11, 16] are associated withhigher complication rates in octogenarians undergoing lungresection. In addition, Port et al. demonstrated a statisticallysignificant shorter length of stay and less ICU admission rateswith VATS over thoracotomy in octogenarians undergoinglobectomy [9]. While we did not seek to find differencesin operative approach in this study, we did not observea difference in complication rates between thoracotomy,VATS, and robotic, likely due to the study size. Minimallyinvasive approaches to lung resection have been shown to beassociated with fewer complications by many authors [9, 19]and should be considered for octogenarians if appropriate.

Long-term survival after lobectomy in the elderly pop-ulation is an important consideration. The calculated 5-year overall survival of 52% in our series was comparableto previous reported 5-year overall survival of 18.2–69.6%[7–17]. Furthermore, for stage IA patients the calculated 5-year overall survival rate was excellent at 78% comparedto 69.6% reported previously [9]. Univariate analysis in our

study failed to reveal predictors of better survival aside fromlower pathologic stage. In this study, there was no statisticallysignificant survival benefit dependent on operative approach.

We have observed that many of our patients are con-cerned with the possible need for a nursing facility (SNF) staypostoperatively. For patients in whom disposition data wereavailable (36/45), 32 (88.9%) were able to be discharged homewith 4 (11.1%) requiring discharge to a SNF. These rates aresimilar to other studies which report that 6% [19] and 16.5%[9] of octogenarians require SNF after lung resection.

Limitations to this retrospective review include patientselection bias, lack of a control group, small size, andvariability of operative approach.The classification of compli-cations as minor or major depending on level of interventionrequired does not reflect patient quality of life and the per-ceived invasiveness of the intervention. Additionally, theseresults may not be reproduced at other centers with differentpatient selection criteria and experience. Our follow-up wasalso limited at 1.7 years.

In today’s society, where an 80 year old male can expectto live an additional 8 years (an 80-year-old female canlive another 9.3 years) [27], carefully selected medicallyfit patients over 80 should be offered anatomic resec-tion for early stage, operable NSCLC as per the NCCNguideline recommendations [3]. We found that employingan intervention-based, validated complication classificationscheme is helpful when discussing expected surgical out-comes within this population (octogenarians) and acrossstudies.

We have also shown that appropriately chosen octoge-narians can undergo lobectomy with encouraging overallsurvival. These data should help physicians and surgeonsunderstand the short-term risks and long-term survivalassociated with lobectomy, provide a framework for futurecomparison to SBRT or wedge resection, and allow surgeonsto counsel older patients more thoroughly.

In conclusion, while 62% of octogenarians undergoinglobectomy had a complication, severe complications usingthe Seely morbidity and mortality complication schemaoccurred in only 15.6% of our study group. In addition, octo-genarians deemed operable by a thoracic surgeon, regardlessof stage or surgical approach, can achieve a reasonable 5-yearsurvival of greater than 50%. Using this data as a foundation,providers can accurately counsel similar patients regardingtheir surgical complication risk and expected survival.
